First season growing dahlias. Delaware Zone 7B. I have 2 cafe au lait plants. (Despite being told they were fussy, they are the only ones that have come up for me out of 5 varieties planted!) is this brown stuff on the leaves cause for concern? It HAS been very hot this June.
Also, is it normal for other dahlias to take this long to sprout?
